K-Cl cotransporters are proteins that lower intracellular chloride concentrations below the electrochemical equilibrium potential. The protein encoded by this gene is an integral membrane K-Cl cotransporter that can function in either a net efflux or influx pathway, depending on the chemical concentration gradients of potassium and chloride. The encoded protein can act as a homomultimer, or as a heteromultimer with other K-Cl cotransporters, to maintain chloride homeostasis in neurons. Alternative splicing results in two transcript variants encoding different isoforms. [provided by RefSeq, Sep 2008]

Cation-coupled Chloride cotransporters, organism-specific biosystemThe cation-chloride cotransporter family (SLC12 gene family) are membrane proteins that cotranslocate chloride (Cl-) with either Na+, K+, or both cations electroneutrally. The general topology of the...

SLC-mediated transmembrane transport, organism-specific biosystemProteins with transporting functions can be roughly classified into 3 categories: ATP-powered pumps, ion channels, and transporters. Pumps utilize the energy released by ATP hydrolysis to power the m...

Transport of inorganic cations/anions and amino acids/oligopeptides, organism-specific biosystemTeleologically, one might argue that inorganic cation and anion transport would be evolutionarily among the oldest transport functions. Eight families comprise the group that transports exclusively i...

These reference sequences are curated independently of the genome
annotation cycle, so their versions may not match the RefSeq versions in the current
genome build. Identify version mismatches by comparing the version of the RefSeq in
this section to the one reported in Genomic regions,
transcripts, and products above.

Transcript Variant: This variant (2) differs in the 5' UTR and 5' coding region, compared to variant 1. The resulting isoform (2, also known as KCC2b) has a distinct N-terminus and is shorter than isoform 1.

The following sections contain reference sequences that belong to a
specific genome build. Explain

This section includes genomic Reference
Sequences (RefSeqs) from all assemblies on which this gene is annotated, such as
RefSeqs for chromosomes and scaffolds (contigs) from both reference and alternate
assemblies. Model RNAs and proteins are also reported here.
